WOODWORKING-TOOL.

Application filed December 7, 1914. Serial No. 875,911.

To all whom it may concern:

Be it known that I, CYRUS L. OAKLEY, a citizen of the United States, residing at Carbondale, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Woodworking-Tools, of which the following is a specification, reference being had to the accompanying drawings.

lhis invention relates to certain improvements in wood working tools and has relation more particularly to a rotating head adapted for grooving or dado work; and an object of the invention is to provide a device of this general character having novel and improved means whereby the cutting action of the device may be readily and conveniently adjusted to meet the requirements of practice.

Furthermore, it is an object of the invention to provide a noveland improved wood working tool including a cutting blade and cutting spurs or teeth adapted for detachable engagement and capable of application or removal one independently of the other.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved wood working tool whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth. 7

The novel features of the invention will be carefully defined in the appended claim.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accom- 4o panying drawings, wherein Figure 1 is an elevational view of an arm and its concomitant parts as comprised in a wood working tool constructed in accordance with an embodiment of my invention;

Fig. 2 is a fragmentary view, partly in front elevation and partly in section, of a wood working tool as herein embodied; Fig. 3 is a sectional view taken substantially on the line 3-3 of Fig. 1; and Fig. 4: is a sectional view taken substantially on the line 44 of Fig. 1.

As disclosed in the accompanying drawings, A denotes an arbor, comprised in my improved head, and on which are adapted to be mounted the arms 1 and 2 of substantially duplicate construction and each being provided at its longitudinal center with an opening 3 through which the. arbor A is adapted to project. In order that the eX- tremities of the arms 1 and 2 may be positioned in substantially the same plane, the central portion of the arm 2 is offset, as at l, to afford a pocket in which is adapted to be accommodated the central portion of the coacting arm 1 and whereby said arms 1 and 2 are maintained in substantially perpendicular relation. The longitudinal extremities of the arms 1 and 2 are disposed in parallelism, as indicated at 5, and one of said parallel faces at the opposite extremities of each of the arms is provided with a longitudinally disposed groove 6 adapted to receive the tongue 7 formed on the rear face of the stem 8 of the substantially L-shape cutter 9, the foot 10 whereof being substantially flush with the adjacent end of the arm and terminating in the cutting edge 11. The stem 8 is also provided with an opening 12 adapted to register with a threaded recess 14 produced in the adjacent face or edge of the arm and through said opening 12 is adapted to be disposed the headed clamping member 15 adapted for threaded engagement with the recess 14 whereby it will be readily perceived that the cutter 9 will be effectively maintained in operative position. It is also to be particularly observed that the cutters 9 are applied to a single arm at opposite sides thereof, for a purpose which is believed to be clearly apparent to those skilled in the art to which my present invention appertains.

Each of the arms 1 and 2 has its marginal portion opposite to the cutter 9 reduced, as at 16, to afford the inwardlybeveled shoulders 17 with which are adapted to coact the correspondingly beveled marginal portions of the plates 18, each of said plates being of such a transverse diameter as to project beyond the side of the arm and to be operatively engaged by the inwardly beveled shoulder 19 of the clamping block 20. It is to be understood that the adjacent marginal portion of the plate 18 is correspondingly beveled, as is believed to be clearly shown in the accompanying drawings. The clamping block 20 is provided with an opening 21 through which is adapted to be projected the headed clamping member 22 adapted for threaded engagement within the recess 23. As herein embodied, the recesses 14: and 23 are in substantial alinement and if required can be created by a continuous bore through the arm. The plate 18 is adapted to project a predetermined distance beyond the outer extremity of the arm and has its projected extremity provided with the teeth 24 and alternately disposed in opposite directions and adapted to coact with the cutter 9 in a manner which is believed to be self-evident. y

In applying the arms 1 and 2 upon the arbor A, the same are adapted to be positioned between the collars 25 suitably affixed to the arbor, and when it is desired to vary the width of cut of the improved tool, it is only necessary to interpose between the overlying portions of the arms 1 and 2 a washer 26 of requisite thickness.

In order that the head may be properly balanced, I find it of advantage to produce in each of the arms at opposite sides of its longitudinal center the alined elongated slots 27 disposed longitudinally of the arms and having disposed therethrough the balancing members 28, herein disclosed as conventional bolts with their coacting nuts. As is believed to be self-evident, the requisite balance can be assured by adjusting the balancing members 28 longitudinally of the arms. The cutters 9 or the plates 18 can each be removed one independently of the other as the requirements of practice may necessitate, and a perfect running balance is afforded by the members 28.

Copies of this patent may be obtained for From the foregoing description, it is thought to be obvious that a Wood working tool constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not Wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

A device of the character described comprising an arm having a central perforation to afford a mounting therefor and having longitudinally disposed elongated slots therein at opposite sides of the opening, balancing members disposed through said slots and detachably engaged with the arm, and cutting members carried by the opposite extremities of the arm.

In testimony whereof I hereunto aiiix my signature in the presence of two witnesses.
